Legal claims defining the scope of protection. Each claim is shown in both the original legal language and a plain English translation.

Claim 1

Original Legal Text

1. A terminal in a mobile communication system supporting carrier aggregation (CA), the terminal comprising: a transceiver configured to transmit and receive signals; and a controller coupled with the transceiver and configured to: receive, from a base station, configuration information for configuring a first cell allocated with a first component carrier (CC), receive, from the base station, configuration information for adding a second cell allocated with a second CC, and communicate with the base station, based on the CA of the first CC of the first cell and the second CC of the second cell, wherein sectors of the first cell are allocated with a same physical cell identifier (PCID), wherein sectors of the second cell are allocated with PCIDs that are different from the same PCID allocated to the sectors of the first cell, and wherein the PCIDs allocated to the sectors of the second cell are different from each other.

Plain English Translation

A terminal in a mobile communication system supporting Carrier Aggregation (CA) includes a transceiver for sending and receiving signals, and a controller. The controller is designed to: 1. Receive configuration data from a base station for a first cell, which uses a first component carrier (CC). 2. Receive configuration data to add a second cell, which uses a second CC. 3. Communicate with the base station by combining these two carriers via CA. A key feature is how Physical Cell Identifiers (PCIDs) are assigned: all sectors within the first cell share the *same* PCID. In contrast, sectors within the second cell are assigned PCIDs that are *different* from each other, and these second-cell PCIDs are also distinct from the PCID of the first cell.

Claim 2

Original Legal Text

2. The terminal of claim 1 , wherein each of the first and second cells includes at least two sectors, and wherein PCID is allocated to each sector.
